Took a bit of searching to find the right WIX part number so I thought I would post it for anyone else looking for it. WIX #33348. The original Jaguar part number is JS660. This is the fuel filter for cars that use the metal filter bowl.
It comes with the big O-ring needed to seal the filter bowl but it doesn't come with the little O-ring to seal the screw. I just bought a pack of generic fuel compatible Viton O-rings. Its a pretty beefy O-ring so you aren't likely going to need to change it very often anyway.
